Cookie compliance integration for Shopify
There is no way to include an external script to Shopify in the checkout, all you can do is to include Cookie-Script code on your Storefront and the Order Confirmation page.
1 Log in to your Shopify Dashboard.
2 Tap on Online Store then Themes.
3 Tap on the Actions button and choose Edit HTML/CSS.
4 Under layout, select theme.liquid.
5 Paste copied Cookie-Script snippet just before the </body> closing tag.
Note
Depending on the theme closing tag could be {/head}, [/header], or other variations of [/head].
6 Tap Save.
Cookie-Script is installed on Shopify now and should be ready for use.
